Android特效 五种Toast具体解释

Toast是Android中用来显示显示信息的一种机制，和Dialog不一样的是，Toast是没有焦点的，并且Toast显示的时间有限，过一定的时间就会自己主动消失。

1.默认效果:

代码:

Toast.makeText(getApplicationContext(), "默认Toast样式",

     Toast.LENGTH_SHORT).show();

2.自己定义显示位置效果:

代码:

toast = Toast.makeText(getApplicationContext(),

     "自己定义位置Toast", Toast.LENGTH_LONG);

   toast.setGravity(Gravity.CENTER, 0, 0);

   toast.show();

3.带图片效果:

代码

toast = Toast.makeText(getApplicationContext(),

     "带图片的Toast", Toast.LENGTH_LONG);

   toast.setGravity(Gravity.CENTER, 0, 0);

   LinearLayout toastView = (LinearLayout) toast.getView();

   ImageView imageCodeProject = new ImageView(getApplicationContext());

   imageCodeProject.setImageResource(R.drawable.icon);

   toastView.addView(imageCodeProject, 0);

   toast.show();

4.全然自己定义效果:

代码

LayoutInflater inflater = getLayoutInflater();

   View layout = inflater.inflate(R.layout.custom,

     (ViewGroup) findViewById(R.id.llToast));

   ImageView image = (ImageView) layout

     .findViewById(R.id.tvImageToast);

   image.setImageResource(R.drawable.icon);

   TextView title = (TextView) layout.findViewById(R.id.tvTitleToast);

   title.setText("Attention");

   TextView text = (TextView) layout.findViewById(R.id.tvTextToast);

   text.setText("全然自己定义Toast");

   toast = new Toast(getApplicationContext());

   toast.setGravity(Gravity.RIGHT | Gravity.TOP, 12, 40);

   toast.setDuration(Toast.LENGTH_LONG);

   toast.setView(layout);

   toast.show();

5.其它线程:

代码:

new Thread(new Runnable() {

    public void run() {

     showToast();

    }

   }).start();
